Abstract
An orbiting satellite can be maintained in a virtual orbit, having an orbital period equal to the natural orbit of a satellite at a different altitude, by equipping the satellite with at least one radial thruster. Radial thrusters on the anti-nadir-facing side of the satellite allow for virtual orbits higher than the natural altitude, while radial thrusters on the nadir-facing side of the satellite allow for virtual orbits lower than the natural altitude. This allows a satellite to evade threats, such as orbital debris and/or hostile spacecraft, without losing its relative position within a satellite constellation or experiencing the diminished services often attendant such maneuvers. Similar techniques can also be used for surveillance of orbiting satellites.
